    There is nothing I hate worse than hitting the brakes and sounding like a bunch of Costa Rican howler monkeys. The rotors (with proper break in) seem to be some of the best at keeping the noise levels low while maintaining some great durability. Maybe not the lightest out there, but definitely worth a gram or two.

    It stops and I'm alive!
    I upgraded my single speed from 160mm to 180mm and wasn't looking for something to break the bank (considering my SS wasn't high end).. but it does the job.. I can be more reckless and faster, and I know this rotor will stop..

    Don't forget the adapter, if you are upgrading to a larger rotor!

    a decent rotor by Shimano
    the rotor looks attractive to me. I personally like one piece silver design for looking, rather than the higher end ice tech etc. There is no issue installing and use it. The only draw back of the Shimano package is the quality of the 6 bolts included are just okay. You need to be very careful when using T25 bids installing it.

    Great value
    The new SLX rotors are the XTR of 2 years ago. I have been riding this set for the last 2 months and have had no warping. I am running 180 mm front and rear and have more stopping power than I need. These are a great buy for the price.

    SLX For the win!
    Best bang for buck. Works with resin or metallic pads. Paired up with SLX brakes these rotors are great.

    Good value
    These SLX rotors really do a nice job, especially for the bucks. I had an Ice Tech rotor that became fouled not too long after I put it on. You never know when that sort of thing might happen. So, since I pay for this stuff myself, why spend the extra money? These rotors work great for the riding I do, downhill switchbacks in rocky, rooty terrain would be the place I need these the most, and they've never failed to perform well.

    Good stopping power and Modulation
    I bought 1 for my front and 1 for my back tire, after using an inferior brand rotor for about 2 years and dealing with the horrendous noise they made. After a quick install and some new pads, I ran through the burn-in process and hung the bike up for the day. Yesterday I took it out and rode about 8 1/2 miles and I LOVED the way these feel! I have full confidence in these rotors and the pads grip them way better than my last rotors. Modulation and feel are excellent as well!

    Does this rotor require the "fixing washer" for installation? Looks like it just comes with the bolts and tightening plates and wondering if this additional piece of hardware is also needed.
    Wilky on May 21, 2016
    BEST ANSWER: NO rotors require the "fixing washers" it is a redundancy to extra double ensure they meet safety regulations. the lock tight on the rotor bolts exists for the same reason, to make sure the bolts don't back out. If your rotor bolts have sufficient lock tight on them then you don't need any other hokey parts. This information provided via the bicycle safety regulations which state all braking related fasteners must have a retention system in place.
    Will this rotor work with Avid BB-7 brakes?
